I have a 2 x Laing DDC-1T Plus.

One of the pumps starts fast and then slows down to the slowest mode for some reason.

I have connected the yellow and black wire to 12v

Can someone help me with this please.

Thank you

Can you make a picture of the connection? Because if it is connected in the righ way, the pump cant slow down. Only reason could be.... the pump grinds or is defective
